"The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2021:1134-1 advisory.

  - Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to
    potentially exploit heap corruption via a crafted HTML page. (CVE-2020-15999)

  - In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the
    user-supplied stride value is trusted for buffer calculations. (CVE-2020-35653)

  - In Pillow before 8.1.0, TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files
    because of certain interpretation conflicts with LibTIFF in RGBA mode. (CVE-2020-35654)

  - In Pillow before 8.1.0, SGIRleDecode has a 4-byte buffer over-read when decoding crafted SGI RLE image
    files because offsets and length tables are mishandled. (CVE-2020-35655)

  - An issue was discovered in Pillow before 8.1.1. TiffDecode has a heap-based buffer overflow when decoding
    crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. NOTE: this
    issue exists because of an incomplete fix for CVE-2020-35654. (CVE-2021-25289)

  - An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an
    invalid size. (CVE-2021-25290)

  - An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is an out-of-bounds read in
    TiffreadRGBATile via invalid tile boundaries. (CVE-2021-25291)

  - An issue was discovered in Pillow before 8.1.1. The PDF parser allows a regular expression DoS (ReDoS)
    attack via a crafted PDF file because of a catastrophic backtracking regex. (CVE-2021-25292)

  - An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
    (CVE-2021-25293)

  - Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the
    reported size of a contained image is not properly checked for a BLP container, and thus an attempted
    memory allocation can be very large. (CVE-2021-27921)

  - Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the
    reported size of a contained image is not properly checked for an ICNS container, and thus an attempted
    memory allocation can be very large. (CVE-2021-27922)

  - Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the
    reported size of a contained image is not properly checked for an ICO container, and thus an attempted
    memory allocation can be very large. (CVE-2021-27923)

  - Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass
    controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c.
    (CVE-2021-34552)
